Anybody using Wilsons or Soundlabs with Pass Labs?

I tried the Aleph series on sound lab A3s and they were excellent within their power rating. Very natural, detailed, with good imaging. If one could find a pair of 1.2s one would be happy indeed.

jameswei, my understanding of the P is that your left and right gain should be set to as far left or 0 as possible while the volume should be as far right or 9.9 as possible making certain that the amp is not being overdriven.

The purpose of these settings is to minimize distortion while receiving maximum volume through the volume control with the shortest signal path possible. The volume control can then likely be wound right out to 9.9 without ever using up the amp.

The gain settings you describe are adding distortion to the listening material and the sound levels I suspect are on the order of minimum 107db @ 16watts continous and a mind numbing/ear killing 119db @ 256watts. So I suggest that you back the gains to 0 or left and the volume further right or 9.9 for improved clarity. I would not be concerned about getting to 9.9 and system integrity, I might be concerned about my ear components.

My P settings are .5mv Helikon, 64db Krell phono stage, 0 gains and full on P volume providing 88-95db intermittent @ 1 metre via 87db efficiency speakers in a 8x16x26' half live/half dead room driven by 10% of the power of your mammoth amp with an Aleph 5. Room RT60 is approximately calculated @ 125hz/.44... 250hz/.68... 500hz/.69... 1Khz/.68... 2Khz/.55... and 4Khz/43

My sound levels are high enough the only thing my system is missing that yours has is the incredible dynamics the Wilson's deliver and almost a full octave of depth.

Way off topic here but the gains should be addressed... otherwise I love the combo!

I use a Pass Labs X-1 preamplifier and a pair of Aleph 2 with Wilson Watt/Puppy 5.1. If you're no bass fetishist this is an excellent combination.

I'm using Aleph 1.2's with a pair of Apogee Duetta Signatures. These replaced a pair of Krell KMA100 Mk 2's.

They are a very synergistic match. Bass is slightly less in quantity but much better in definition. The mids and highs are far superior and sweet.

Yes - I did. I tried a Pass Lab X600 with a pair of Sound Lab Auras (similar to Milenium series, but made of steel like Ultimate).

I also got to compare the X600 with Krell KSA 300S and Atma-Sphere MA1 mkII.2 OTL tube amps.

The results:
Atma-Sphere had the overall best performance, with the Krell a distant second. The Pass amp had NO BASS whatsoever to speak of. I suspect the Pass amps do not like the high impedances that occur in the mid-bass region.

DO NOT recommend you pair the Pass amps with Sound Lab speakers. However, I will say that the midrange and upper frequency performance was outstanding.
